Warning: Cheese May Be Bad for Your Health

By Dr. Susan Calvin / August 18, 2018

Cheese is everyone's favorite food. It's cheap, tasty, and you can easily cook it. But could there be a dark side to cheese?

Since 1980, the US obesity rate has risen proportionately to the increase in consumption of cheese, and Americans are now consuming at least 200 calories of cheese each day. Research published by Environmental Working Group found that adults who consumed high levels of cheese for just two weeks had increased levels of carcinogens, raising their risk of heart disease.


"In the United States, cheese has shown big gains in popularity, and this trend is expected to continue as consumption is projected to increase from 1.5 million tons in 2003 to 2.5 million tons by 2010" write the Environmental Working Group researchers in an article published in the Journal of the American Dietetic Association.

Environmental Working Group said it did not have enough data to define how much cheese is too dangerous, but said the risk grows with the amount consumed. Analysis suggested that a 50-gram portion of cheese daily - or about 1.75 ounces - increases the risk of colorectal cancer over a lifetime by about 18 percent.

According to the Environmental Working Group, the "first-ever tests of cheese show that they are likely the most carcinogens-contaminated substance in the U.S. food supply." Carcinogens is actually a very toxic chemical that can contribute to cancer and other complications. The problem with carcinogens is that once it enters our system, it can take a very long time until it leaves. Grimly, the half-life of carcinogens is about 7 to 11 years!

Over the past 30 years, the FDA has received thousands of consumer complaints about cheese due mostly to neurological symptoms such as headaches, dizziness, memory loss, and, in rare cases, epileptic seizures. Many studies have shown cheese to be completely harmless, while others indicate that it might be responsible for a range of cancers. Until we know for sure, Environmental Working Group recommends avoiding cheese.
